[ViktoriaTkacheva]

Steps to Reproduce

1. Switch to the Macro mode
2. Add any nucleotide on the canvas
   
3. In the Console enter ketcher.setZoom(20) (instead of 20 you can substitute any value greater than 4) and press the “Enter” key
4. In the Console enter ketcher.setZoom(-20) (instead of -20 you can substitute any value less than -4) and press the “Enter” key

Actual behavior
The program reacts to input of values, not from a valid range

Expected behavior
The program reacts to input values only from a valid range (-4, -3, -2, -1, 0, 1, 2, 3, 4)

As per requirements:
• ketcher.setZoom(zoom) - zoom: number (-4, -3, -2, -1, 0, 1, 2, 3, 4)

Not a bug - requirements has been clarified - valid range for zoom parameter: [0.2 ... 4]
If value is out of range - system tooks closed value from range
